BALLERUP, Denmark, Oct. 20, 2026 (GLOBE NEWSWIRE) -- LiqTech International, Inc. (NASDAQ:LIQT) ("LiqTech" or the "Company"), a clean technology company specializing in advanced filtration technologies, today announced an order from Shanghai Qiyao Environmental Technology Co. Ltd. for two water treatment units for intelligent control by exhaust recycling (iCER) marine engine applications. Delivery is scheduled for December 2026.

The order marks Shanghai QiYao Environmental Technology first purchase of LiqTech iCER water treatment systems and expands an existing relationship previously focused on marine scrubber water treatment. It follows LiqTech’s other recent marine orders since its JV in China established in November 2024, including scrubber water treatment units in May 2025, dual-fuel engine water treatment systems announced in November 2025, and four exhaust gas recirculation (EGR) water treatment systems announced in June 2026.

"This order is an important example of how we can expand established marine customer relationships into additional applications," said Fei Chen, President and Chief Executive Officer of LiqTech. "Our investments in adapting our silicon carbide membrane technology for iCER and EGR systems are broadening our addressable market. We see opportunities to build a more diversified and repeatable marine business as customers adopt new engine technologies."

In iCER applications, water is used to cool and clean exhaust gas before part of the gas is recirculated into the engine. Soot, oil, and other contaminants must be removed from the circulating water. LiqTech’s water treatment units use proprietary silicon carbide ceramic membranes to separate these contaminants and support water reuse and reliable system operation.

LiqTech’s silicon carbide membranes combine fine-particle filtration with chemical resistance, temperature tolerance, and mechanical durability suited to demanding marine environments. The Company’s experience from more than 170 marine scrubber installations provides an established foundation as it extends its offering to iCER and EGR applications.

LiqTech’s joint venture in China supports local engineering, sourcing, assembly, and service, while core silicon carbide membranes continue to be manufactured in Denmark. This operating model is intended to improve responsiveness to customers and shipyards in the region.

"Our local presence in China enables closer coordination with customers throughout specification, delivery, and service," Chen added. "Combined with our filtration expertise, it supports our strategy to deepen existing relationships and pursue additional opportunities across scrubber, iCER, and EGR applications."
